f98e1b8071 With these changes sh(1)'s trap command should be POSIX-compliant,
while remaining (becoming :) compatible with other popular shells.
Specifically these changes include:

1) Implement 'trap -l' to get a list of valid signals names.  This
   is useful if you wanted to do something like reset all signal
   handlers to there defaults values, in which case something like
   this will do the trick.

	trap `trap -l`

2) Reformat the output of 'trap' so it can be saved and later eval'd
   to restore the saved settings.

3) Allow the use of signal names as well as signal numbers.

4) Fix trap handling of SIGCHLD so that commands like the following
   (albeit, contrived) won't cause sh(1) to recurse ad infinitum.

	trap uname 0 20

5) Make variables static that are used only in trap.c.

6) Minor 'style(9) police' mods.

a41f1d080d Don't use _POSIX_PATH_MAX to limit the size of the path, instead
use 'getcwd(NULL, 0)' just as pwd(1) does.

958ba632fa Make sh(1) a little braver in the face of adversity. sh(1)
now handles the getpwd() init problem the same way as bash
and ksh do.  Also while I was in here, I cleaned up the format
a little, removed some unnnecessary #if SYMLINKS cruft, and
changed the pwd builtin to use getcwd(3) as Joerg suggested.

getopts should now work as expected.  This fix was in the NetBSD
code that I was merging from but missed getting into FreeBSD's
version because of 'drain bamage' on my part.

2ffc1ec6ca The manual page of df called cd9660 file systems by the name
isofs while the df command itself used the name iso9660fs or
        cdfs. Both of these were inconsistent with the name cd9660 which
        is used by the mount command. I modified df to recognize all of
        the names cd9660, cdfs, isofs, and iso9660fs, and take them all
        to refer to the same thing. Naturally I added a note of this
        behaviour in the manual page too.

a68e018a5e Fixed `stty [-]extproc'. It set extproc to a semi-random state (always
off if there are no other options, always (?) on if another option that
changes the state is processed earlier).

ad66f7ee71 Bruce says: "You have been programming in the kernel for too long :-)."
and he's right ... I forgot about this floating point stuff you can
use in user-land :-)

Increase precision of duration to microseconds.
No heuristics to avoid overflow in calculation needed - just depend
on DBL_MAX being a bit larger than LONG_MAX.

Use double instead of `struct timeval' in dd.h so that everything
doesn't have to include <sys/time.h>.

Fixed style bugs in recent and old FreeBSD changes.

7a2ce49ee0 Back out rev 1.7 which was to fix PR#1206 (to be reopened).
This patch causes too many side effects, one of which bites hard is
when interrupting a 'make fetch' in the ports tree (PR#1990).
This whole area is a real can of worms....

This most definately should go into 2.2

db91faacb6 Implement a -c option to ps to display the short command name instead of
the full argument vector.

I've bumped into a few things that expected this switch to be present,
the most recent was the snmp package in ports.  I'm not 100% sure of the
origins of this, but Linux has it, so does the "BSD-compatable" version
of ps on our SVR4 systems (so I assume SunOS has it too).

the 4.4 lite 2 tape as well.  There are now only two diffs between
NetBSD's cat and FreeBSD's cat:
	getopt return value is -1 on NetBSD and EOF on FreeBSD.
	NetBSD has added setlocale calls before anything else.
